Install, PS2 games are harder than Wii games since you have to take your game disk and rip it to your computer then patch the file and then move it to the hard drive. It is convenient for not having to change disks all the time, but the ps2's usb port has 1.1 speed, so the fmv on the hard drive stutters at times, so I preper the game disks for ps2. Wii games are easy, wiiflow let's you put the disk in and add it to your hard drive.
